What is claimed is: sure or window for the sake of illustration. This 1. Operating mechanism for the closures of window is designated by the numeral I which is vehicles, and the like, comprising a fluid motor guided vertically in channel ways 2 on the door 3. having an elongated The window glass is elevated by means of a ated rod slidably guided through a bearing in one fluid motor, preferably one utilizing an air presend thereof, power transmission means including sure diflerential in which the low pressure ina lever pivotally connected to the outer end of fluence of the intake manifold may be used. As the rod, said one end of the chamber being free illustrated, the motor comprises a cylinder 4 and to swing to accommodate the arcuate travel of a piston I. The piston rod 6 is operatively conthe point of pivotal nected to the window to elevate and lower the and lever, means pivotally mounting the opposame as desired. The connection disclosed emsite end of the chamber, the first end of the bodies a bell crank lever 1 pivoted on a stud 8 chamber having a arried y a bracket 9, and to this stud is fixed finger slidably received in the slot, said transone end of a convolute spring I0 to counterbalverse slot being formed in an integral part of once the sash,. the opposite end or the spring the rod bearing adjacent the rod whereby guidbeing fixed to the sash connected arm or the bell crank. The cylinder is yieldably mounted on a support bracket or track part II through a bracket or roller part I 3 and a tension and compression member l2 in the form of a spring leaf, the arrangement providing in eflfect a Z-shaped support wherein the parts are in substantially stacked relationship. This mounting permits the opposite end of the cylinder with its protruding piston rod to swing in a vertical plane for acin a slot 4 the motor carthis rolling action will slot I B as it rises and piston rod and the bell clarity. It is obvious that chamber with a fluid actuconnection between the rod transverse slot, and a guiding ing support of the rod, piston and cylinder assembly is provided substantially midway oi the assembly when the rod is in its extended position and close to the longitudinal axis the assembly to reduce vibration and torque to a minimum.

2. Operating mechanism for the closures of vehicles, and the like, comprising a fluid motor having an elongated chamber with a fluldactuated rod slidably guided through one end thereof, power transmission means including a lever pivotally connected to the outer end of the rod, said one end of the chamber being free to swing to accommodate the arcuatetravel of the point of pivotal connection between the rod and lever, a supporting bracket for mounting the opposite end of the chamber, a bracket part flxed on said opposite end of the chamber and overlying the bracket, and an intermediate spring leai. flxed at one end to the bracket and at the opposite end to the bracket part whereby said bracket, said bracket part and said spring leaf are in substantial stacked relationship.

3. Operating mechanism for the closures of vehicles, and the like, comprising a fluid motor having an elongated chamber with a fluid actuated rod slidably guided through one end thereof, power transmission means including a lever pivotally connected to the outer end of the rod, said one end of the chamber being free to swing to accommodate the arcuate travel of the point of pivotal connection between the rod and lever, a supporting bracket for mounting the opposite end of the chamber, a bracket part fixed on said opposite end of the chamber and overlying the bracket, and a spring leaf fixed at one end to the bracket and at the opposite end to the bracket part, the bracket part being curved to rock upon the bracket.

4. Operating mechanism for the closures of vehicles, and the like, comprising a fluid motor having an elongated chamber with a fluid actuated rod slidably guided through one end thereof, power transmission means including a lever pivotally connected to the outer end of the rod, said one end of the chamber being free to swing to accommodate the arcuate travel of the point of pivotal connection between the rod and lever, means guidingly supporting said one end of the chamber against lateral movement during its swinging motion, and means mounting the opposite endof the chamber for such swinging movement, said last means comprising a support having a track part, a roller part on said opposite end of the cylinder mounted on said track part for longitudinal movement thereon during swinging motion of the cylinder, and a member connecting the roller part to the track part for holding such parts operative.

5. Operating mechanism for the closures of vehicles, and the like, comprising a fluid motor having an elongated chamber with a fluid actuated rod slidably guided through one end thereof, power transmission means including a lever pivotally connected to the outer end of the rod, said one end of the chamber being free to swing to accommodate the arcuate travel of the point of pivotal connection between the rod and lever, means guidingly supporting said one end of the chamber during its swinging motion, and means mounting the opposite end of the chamber, said last means comprising a support having a track part, a part on said opposite end of the cylinder rollingly mounted on said track part for longitudinal movement thereon during swinging motion of the cylinder, and a tension and compression member connecting said cylinder part to the track part for holding such parts operative.

6. Closure operating mechanism comprising a fluid motor having a piston and cylinder, means guidingly supporting the cylinder at one end against lateral sway and body torque while allowing for vertical swinging and bodily motion in a constant longitudinal plane, and a substantially Z-shaped support mounting the cylinder at its opposite end, the angular bar of the Z-shaped support being of a resilient nature.

7. Window operating mechanism adapted for automotive installation, comprising, a fluid motor having a cylinder and a piston therein with a rod extending therefrom, means at one end of said cylinder for mounting it upon a fixed member, said means permitting swinging of said cylinder and bodily longitudinal movement thereof during actuation of said fluid motor, an operative connection between said piston and a window including a lever pivoted to the piston rod, the other end of said cylinder having a slotted guideway adjacent the egress opening in the cylinder head for said piston rod, and a fixed guide slidably embraced by said guideway for maintaining said fluid motor in a constant plane of operation during such swinging and bodily longitudinal movement as it rocks the lever to actuate the companion window.

8. Closure operatin mechanism adapted for 1 installation in the narrow well of an automobile window structure, comprising a fluid motor having a cylinder and piston, an operative connection between said closure and said motor, a mounting for said motor having a flexible member and connecting said motor to said window structure while normally allowing bodily swinging and shifting of said motorin various directions, and guide means for restricting the fiexure of said flexible member to a constant plane substantially parallel to the walls of said window well whereby said mechanism will be restrained from contact with said walls.
